Picture this, ye with poor vision...if you can:

Tomorrow, there is some kind of disaster from which our capitalistic society cannot recover. And that's not even the bad part. Corporations close. Manufacturers no longer manufacture. Eventually the world's supply of contact lenses runs out and you are left with only your glasses. What if you slip climbing down a mountain and crack them on a rock, or if when you are swinging across the deserted remnants of the Brooklyn Bridge, you drop your specs into the river below?

Those with good eye sight will have the advantage over us. My squinty friends, I think it's best we kill them now in guarded anticipation for our eventual blindness. What say you?
